After finding an old non-working A: drive in the basement, I wanted to try and make a neat little gift for my nephew (get him started at an early age :P ) using it. I figured at his age he'd enjoy watching a color changing light, but at the same time I wanted to make the gift functional in some way. I decided to make the A: disk into a dollar bill holder, while the drive would be the bank.
1. Old A: Disk Drive
2. A: Disk
3. Small magnet (1 or 2)
4. Two Rainbow Flashing 5mm LED (Blinking LED)
5. Foil Insulation Tape
6. A 100 ohm resistor
7. Electrical wire
8. Solder and Soldering Iron
9. Strong Glue (Gorilla Glue)
10. Exacto Knife
11. Flat and star headed screwdrivers
12. Wire cutters/strippers (or scissors)
13. Thin ferrous scrap metal (if you only want to use one magnet)
15. Small momentary switch
16. 9v battery clip
17. 9v battery
18. Fluorescent light diffusing panel
19. Well vented area
21. Electrical tape
Warning: There are dangerous fumes involved with this project. Be careful with all sharp, hot, and harmful items. Use a gas mask if you have one...
Step 1: Dollar Bill Holder
First we start off making the dollar bill holder. I had already made it, but just follow the steps I lay out before you and refer to the photos below and you can easily make one too.
1. First of all, get an old A: disk that you don't care about (hence the AOL disk).
2. Insert a flat head screwdriver into one of the sides of the disk (through the seam).
3. Gently pry the disk open (top and sides). Leave the bottom attached. If anything falls out, find it and put it aside.
4. Using a small piece of a toothpick, prop the disk open as shown in the photos.
5. Take out the metal disc from the inside and using scissors, cut all the black material off the metal disc.
6. Glue the disc into the groove that it belongs in. Also glue the "write/locked" tab in the corner onto the track it came from.
7. Allow glue time to dry. Start warming up your soldering iron.
8. Once the glue has dried, take your soldering iron and melt a hole in the center/top of the disk (on the inside). Do the same on the opposite side (once again, on the inside).
9. Glue the magnet into one of the holes. Allow it to dry.
10. Flip the disk over and either glue a small piece of the ferrous scrap metal into the hole or another magnet (depening on how many bills you plan on placing in each disk). Allow glue to dry.
After the glue has dried completely, you will have you're very own dollar bill holder. Just slide the money in and close the "clasp" of the holder...
Next, the disk holding bank.
